Chapters three and four were mainly about closure and how comics use time to help the reader understand panels. McCloud explains that closure is the space that separates each panel. Panels can be separated by different amounts of space, long or short. Between panels, the reader uses his/her imagination in decided what is happening, and what the action taking place looks like between panels. McCloud explains that the readers participation is a powerful force in comics.
McCloud breaks down closure into six categorizes. There is moment-to-moment, action-to-action, subject-to-subject, scene-to-scene, aspect-to-aspect, and non-sequitur. McCloud goes on to examine the two most used categories used in making comics. They are action-to-action and subject-to-subject. He also goes on to explain that comics from Japan use many of these categories.
Using these six categories of closure, a comic can tell a story in many different ways. The story can be in much detail, or have very simple detail. McCloud uses a very big panel to show a family in a room. There is a picture being taken, people on the sofa, and two gentlemen playing chess. McCloud explains that the panel is always read from left to right, and that time flows through this panel so it will make sense when you read it. Word bubbles are placed in left to right order in which the author wants you to read them in. Timing between panels can create a dramatic effect when needed. The two main concepts McCloud wants us to understand are timing and closure between panels.
